Thanks for this discussion... after reading Domenic's slides, watching his talk, and going through the questions here and on the gist, I've filed a bug to try to move Enyo's async implementation to promises after our next release. (https://enyojs.atlassian.net/browse/ENYO-2700 https://enyojs.atlassian.net/browse/ENYO-2700) Currently, our code is more like the jQuery 1.5 implementation, but it really lacks the nice error semantics that Promises/A+ has.
